Device and method for individualizing fish and orienting head, tail, ventral and dorsal

Abstract

The invention discloses a device and a method for fish singularizing, head and tail orientation and belly and back orientation. The device comprises a fish conveying mechanism, a singularizing mechanism, an image acquisition mechanism, a belly and back orientation mechanism, a head and tail orientation mechanism and a fish standing mechanism; the fish conveying mechanism is composed of a pluralityof conveying belts, and fishes are scattered through differential speed; the singularizing mechanism is provided with a plurality of height limiting mechanisms and width limiting mechanisms which areinstalled on the two sides of the conveying belts and sequentially gather fishes towards the center; the image acquisition mechanism is used for acquiring images of the fishes and analyzing orientation information; the belly and back orientation mechanism can perform belly and back correction on the fishes according to the orientation information and separate the fishes with wrong head and tail orientation; and the head and orientation mechanism and the fish standing mechanism are connected to the tail end of a conveying platform, the fishes with wrong head and tail orientation fall into a head-tail steering groove under the action of gravity and a ratchet wheel roller, head-tail steering is achieved, and the fishes are changed into an erected state through a gradual change sliding way. Aiming at the problem that fish viscera removing processing needs manual auxiliary orientation and single feeding, the device achieves single feeding and head-tail and belly-back oriented feeding of fishes.

Description

technical field [0001] The invention relates to the technical field of aquatic engineering, in particular to a device and method for singulating fish and orienting its head, tail, ventral and dorsal. Background technique [0002] my country is the world's largest producer of aquatic products, accounting for about 30% of the world's total output. In 2018, the total output of aquatic products in the country was 64.5766 million tons, of which the total amount of aquatic products processed was 21.5685 million tons, the processing rate was 41.09%, and the processing rate of seawater products was 63.58% %, and the processing rate of freshwater products is 17.56%. The aquatic product processing industry has developed rapidly. The labor cost of the aquatic product processing industry has risen rapidly, accounting for about 60% of the labor cost in 2016. The production mode of my country's aquatic product processing industry is labor-intensive, the degree of mechanization and automa...

Problems solved by technology

[0005] In order to overcome the problem in the prior art that fish need to be manually fed one by one in the process of removing viscera, the present invention adopts a device and method for singulating fish and orienting the head, tail, abdomen, and back to realize the individualization of fish and the directional feeding of the head, tail, abdomen, and back
